Almeria 68000 [1]

Mephisto Almeria,
a set of dedicated chess computer modules by Hegener & Glaser released in 1988 for their Mephisto module systems. As further development of Richard Lang's Mephisto series and successor of Mephisto Roma, Mephisto Almeria won the fourth consecutive title for Richard Lang in charge of Mephisto - at the WMCCC 1988 in Almería, Spain, which were infact three separate titles, the World Micro Software Champion of fthe Software Group, where an experimental Almeria program played [2], the World Micro Manufacturers (Team) Champion of the Manufacturers Group, which was a duel of four Mephistos versus four Fidelitys including a multi-processor machine, and the Single-CPU World Microcomputer Chess Champion of the Commercial Group, with three programs competing. Short after, the tournament machine played the ACM 1988 as Mephisto X and became third with 2½/4 only losing from winner Deep Thought, a draw versus Cray Blitz, and wins versus AI Chess and Sun Phoenix. Almeria further won the First International Chess-Computer Tournament in the USSR 1989 in Moscow, and also played humans at Netherlands-vs-Computers-1989, the Aegon 1989, and the Aubervilliers Rapid Open 1989.


Despite small improvements in various game phases due to a tweaked search and evaluation, and an enhanced 60,000 ply opening book with 7,000 variations, Mephisto Almeria was the first released Lang program using a transposition table, in total up to 1 MiB of RAM.


Three versions were built, a 68000 version, and beside the normal 68020, the limited edition Mephisto Almeria Tournament machines [3] .
